System class This enclosed version is not suitable for a Class II system without FG; use the Class I arrangement with FG. Integration use Medical power conversion for applications such as oral irrigators, hemodialysis equipment, medical monitors, sleep-apnea devices, pumps and electric beds. BF use requires appropriate complete-system consideration. Main DC Output Nominal main output 12 V. Forced-air current and power 33.3 A / 399.6 W; 25 CFM external airflow. Convection current and power 20.8 A / 249.6 W, subject to the input-voltage and temperature curves. Ripple and noise, maximum 120 mVp-p. Main-output voltage adjustment 11.4–12.6 V. Voltage tolerance ±3.0%, including set-up tolerance, line regulation and load regulation. Line / load regulation ±0.5% / ±1.0%. Efficiency, typical 91.5%. Use the exact model ratings above; the series designation is not a substitute for its printed wattage. Forced-air ratings are cooling-dependent continuous ratings, not an unrestricted overload or peak-power allowance. Unless specified otherwise, values are measured at 230 VAC, rated load and 25°C. Ripple/noise uses 20 MHz bandwidth and a 12-inch twisted pair terminated with parallel 0.1 µF and 47 µF capacitors. Input and Timing Input range 80–264 VAC or 113–370 VDC; 47–63 Hz AC. Apply the input derating curve. Power factor Built-in active PFC; at full load, PF >0.94 at 230 VAC and >0.98 at 115 VAC. Input current, typical 4.2 A at 115 VAC; 2.1 A at 230 VAC. Cold-start inrush, typical 35 A at 115 VAC; 70 A at 230 VAC. Set-up / rise time 1000 ms / 30 ms at 230 VAC; 1500 ms / 30 ms at 115 VAC, full load. Hold-up time, typical 16 ms at both 230 VAC and 115 VAC, full load. Leakage current Earth leakage <200 µA at 264 VAC / 50 Hz; touch current <70 µA at 264 VAC, measured from primary input to DC output. No-load power Less than 0.5 W by PS-ON control. Protection and Auxiliary Outputs Short circuit / overload Short-circuit protection; overload at 105–135% of rated output power. Hiccup mode recovers automatically after the fault is removed. Overvoltage Threshold 13.2–15.6 V; output shuts down and requires re-power on to recover. Overtemperature Output shuts down and recovers automatically after temperature decreases. 5 V standby 5 V, 0.6 A without a fan or 1 A with 25 CFM; tolerance ±2%, maximum ripple 120 mVp-p. These are cooling-qualified standby limits. 12 V fan supply 12 V / 0.5 A for driving a fan. Tolerance −15% to +10% at 35% main-output rated current with 25 CFM. Use the dedicated CN12 polarity below. Control, Status and Remote Sense PS-ON high (2–5 V) turns the main output on; low (0–0.5 V) turns it off. The PG TTL signal goes high 10–500 ms after power set-up and goes low at least 1 ms before output falls below 90% of its rated voltage, providing the listed power-good/power-fail indication. CN11: TKP DH2I-2X2 or equivalent; pin 1 −S, pin 2 +S, pin 3 DC COM, pin 4 PG. The −S/+S pins are the remote-sense connections; this section does not specify a numerical cable-drop compensation limit.

Integration use Medical power conversion for applications such as oral irrigators, hemodialysis equipment, medical monitors, sleep-apnea devices, pumps and electric beds. BF use requires appropriate complete-system consideration. Main DC Output Nominal main output 27 V. Forced-air current and power 14.9 A / 402.3 W; 25 CFM external airflow. Convection current and power 9.3 A / 251.1 W, subject to the input-voltage and temperature curves. Ripple and noise, maximum 200 mVp-p. Main-output voltage adjustment 25.6–28.4 V. Voltage tolerance ±1.0%, including set-up tolerance, line regulation and load regulation. Line / load regulation ±0.5% / ±1.0%. Efficiency, typical 93.5%. Use the exact model ratings above; the series designation is not a substitute for its printed wattage. Forced-air ratings are cooling-dependent continuous ratings, not an unrestricted overload or peak-power allowance. Unless specified otherwise, values are measured at 230 VAC, rated load and 25°C. Ripple/noise uses 20 MHz bandwidth and a 12-inch twisted pair terminated with parallel 0.1 µF and 47 µF capacitors. Input and Timing Input range 80–264 VAC or 113–370 VDC; 47–63 Hz AC. Apply the input derating curve. Power factor Built-in active PFC; at full load, PF >0.94 at 230 VAC and >0.98 at 115 VAC. Input current, typical 4.2 A at 115 VAC; 2.1 A at 230 VAC. Cold-start inrush, typical 35 A at 115 VAC; 70 A at 230 VAC. Set-up / rise time 1000 ms / 30 ms at 230 VAC; 1500 ms / 30 ms at 115 VAC, full load. Hold-up time, typical 16 ms at both 230 VAC and 115 VAC, full load. Leakage current Earth leakage <200 µA at 264 VAC / 50 Hz; touch current <70 µA at 264 VAC, measured from primary input to DC output. No-load power Less than 0.5 W by PS-ON control. Protection and Auxiliary Outputs Short circuit / overload Short-circuit protection; overload at 105–135% of rated output power. Hiccup mode recovers automatically after the fault is removed. Overvoltage Threshold 29.7–35.1 V; output shuts down and requires re-power on to recover. Overtemperature Output shuts down and recovers automatically after temperature decreases. 5 V standby 5 V, 0.6 A without a fan or 1 A with 25 CFM; tolerance ±2%, maximum ripple 120 mVp-p. These are cooling-qualified standby limits. 12 V fan supply 12 V / 0.5 A for driving a fan. Tolerance −15% to +10% at 35% main-output rated current with 25 CFM. Use the dedicated CN12 polarity below. Control, Status and Remote Sense PS-ON high (2–5 V) turns the main output on; low (0–0.5 V) turns it off. The PG TTL signal goes high 10–500 ms after power set-up and goes low at least 1 ms before output falls below 90% of its rated voltage, providing the listed power-good/power-fail indication. CN11: TKP DH2I-2X2 or equivalent; pin 1 −S, pin 2 +S, pin 3 DC COM, pin 4 PG. The −S/+S pins are the remote-sense connections; this section does not specify a numerical cable-drop compensation limit.

  MEAN WELL RPS-300 series: Enclosed Medical AC/DC Power Supply - RPS-300-15-C

  MEAN WELL RPS-300-15-C is a case-enclosed medical AC/DC power supply with active PFC and a nominal 15 V output. It provides up to 20 A / 300 W with the specified forced-air cooling, subject to input and ambient derating. The -C convection curve is limited to 180 W at temperatures up to 40°C, then derates further. Auxiliary standby and fan outputs, PS-ON, power-status signalling and remote sense support system integration. Product Datasheet Download MEAN WELL RPS-300 Datasheet (PDF) The RPS-300 section is on PDF pages 1, 2, 3, 4, 5, 6, 7. Refer to the complete mechanical drawings and notes when planning installation. Model and Configuration Complete model RPS-300-15-C Product type Single-output enclosed medical AC/DC power supply with active PFC. Model code RPS-300 identifies the series; 15 is the nominal DC voltage; the -C suffix identifies the enclosed casing version. The 300W rating requires forced cooling and the specified input and ambient conditions. The model is not supplied as a top-fan or side-fan variant by this code; the cooling fan shown in the installation drawing is external. Primary-to-secondary insulation is 2 × MOPP. Suitability for BF applications requires appropriate consideration of the complete medical system; the component approval is not a guarantee of finished-equipment BF compliance. Model-Specific DC Output DC output voltage 15 V Current range, convection 0–13.33 A; subject to the enclosure and temperature limits below. Current range, forced cooling 0–20 A at 20.5 CFM. Printed output power ratings 200 W with convection; 300 W at 20.5 CFM. Apply all derating limits; the two modes are not interchangeable. Output adjustment 14.25–15.75 V, main output via SVR1. Ripple and noise, maximum 120 mVp-p. Voltage tolerance ±3.0%; includes set-up tolerance, line regulation and load regulation. Line / load regulation ±0.5% / ±1.0%. Efficiency, typical 90% at the standard measurement conditions. The catalogue lists rounded current and power values independently. Respect both limits and the lower allowable load imposed by cooling, input voltage and ambient temperature; do not increase a rating by recalculating voltage × current. Unless otherwise stated, specifications are measured at 230 VAC, rated load and 25°C ambient. Ripple/noise is measured with 20 MHz bandwidth and a 12-inch twisted pair terminated by parallel 0.1 µF and 47 µF capacitors. Input and Start-Up Input range 90–264 VAC or 127–370 VDC; 47–63 Hz AC. Power factor, typical >0.93 at 230 VAC; >0.98 at 115 VAC, full load. Input current, typical 3.5 A at 115 VAC; 1.8 A at 230 VAC. Cold-start inrush, typical 35 A at 115 VAC; 70 A at 230 VAC. Set-up / rise time 2500 ms / 30 ms at 230 VAC; 3000 ms / 30 ms at 115 VAC, full load. Hold-up time, typical 13 ms at 230 VAC and 115 VAC, full load. No-load consumption <0.5 W by PS-ON control. The input-voltage load curve at 60 Hz permits 80% at 90 VAC, rising linearly to 100% at 115 VAC and remaining at 100% through 264 VAC. Apply this limit together with the thermal curves. The functional block diagram identifies a 65 kHz PFC stage and 70 kHz PWM stage. Protection Short circuit / overload 105–135% of rated output power; hiccup mode, with automatic recovery after the fault is removed. Overvoltage 16.2–18.5 V; output shuts down and requires re-powering to recover. Overtemperature TSW1 shuts down the output and recovers automatically after temperature decreases. TSW2 shuts down the output and requires re-powering to recover. Standby, Fan Supply and Control Signals 5 V standby output 5 V at 0.6 A without a fan or 1 A with 20.5 CFM cooling; tolerance ±2%; maximum ripple 150 mVp-p. Fan auxiliary supply 12 V / 0.5 A; tolerance −15% to +10% at a main-output load of 20% of the 20.5 CFM rated current. PS-ON logic Power ON: High, 2–5 V. Power OFF: Low, 0–0.5 V. Power Good / Power Fail TTL goes high after a delay greater than 10 ms and less than 500 ms after power set-up. It goes low at least 1 ms before output falls below 90% of nominal. The fan supply is dedicated to an additional external fan that cools this power supply, supports full-load delivery and promotes service life. Do not use it to drive other devices. Remote sense is provided at CN100: pin 1 is −S and pin 2 is +S; pin 3 is DC COM and pin 4 is PG. Follow the manufacturer installation instructions for sense wiring. This section does not specify a numerical line-drop compensation allowance or a separate PF connector pin. Cooling, Temperature and Environment Working temperature −30 to +70°C, with mode-specific derating; horizontal orientation. Operating humidity 20–90% RH, non-condensing. Storage −40 to +85°C; 10–95% RH, non-condensing. Temperature coefficient ±0.03%/°C over 0–50°C. Vibration 10–500 Hz, 2 G; 10 min per cycle, 60 min each on X, Y and Z. Operating altitude Up to 4000 m, with additional thermal derating above 2000 m. For this enclosed -C type, the horizontal convection curve is limited to 180W up to 40°C and falls to 100W at 60°C. The convection curve ends at 60°C; the 70°C endpoint belongs to forced cooling. With 20.5 CFM forced airflow, the common RPS-300 / RPS-300-C curve permits 300 W through 50°C, then falls to 150 W at 70°C. This is a cooling-dependent continuous rating, not a timed pulse or a duty-cycle peak allowance. Above 2000 m, reduce the allowable ambient temperature by 3.5°C per 1000 m for fanless operation or 5°C per 1000 m for fan-cooled operation. Observe the lower load allowed by all curves.

Model and Configuration Complete model RPS-300-48 Product type Single-output PCB medical AC/DC power supply with active PFC. Model code RPS-300 identifies the series; 48 is the nominal DC voltage; no type suffix identifies the PCB version. The 300W rating requires forced cooling and the specified input and ambient conditions. The model is not supplied as a top-fan or side-fan variant by this code; the cooling fan shown in the installation drawing is external. Primary-to-secondary insulation is 2 × MOPP. Suitability for BF applications requires appropriate consideration of the complete medical system; the component approval is not a guarantee of finished-equipment BF compliance. Model-Specific DC Output DC output voltage 48 V Current range, convection 0–4.17 A; subject to the enclosure and temperature limits below. Current range, forced cooling 0–6.25 A at 20.5 CFM. Printed output power ratings 200.2 W with convection; 300 W at 20.5 CFM. Apply all derating limits; the two modes are not interchangeable. Output adjustment 45.6–50.4 V, main output via SVR1. Ripple and noise, maximum 250 mVp-p. Voltage tolerance ±2.0%; includes set-up tolerance, line regulation and load regulation. Line / load regulation ±0.5% / ±1.0%. Efficiency, typical 93% at the standard measurement conditions. The catalogue lists rounded current and power values independently. Respect both limits and the lower allowable load imposed by cooling, input voltage and ambient temperature; do not increase a rating by recalculating voltage × current. Unless otherwise stated, specifications are measured at 230 VAC, rated load and 25°C ambient. Ripple/noise is measured with 20 MHz bandwidth and a 12-inch twisted pair terminated by parallel 0.1 µF and 47 µF capacitors. Input and Start-Up Input range 90–264 VAC or 127–370 VDC; 47–63 Hz AC. Power factor, typical >0.93 at 230 VAC; >0.98 at 115 VAC, full load. Input current, typical 3.5 A at 115 VAC; 1.8 A at 230 VAC. Cold-start inrush, typical 35 A at 115 VAC; 70 A at 230 VAC. Set-up / rise time 2500 ms / 30 ms at 230 VAC; 3000 ms / 30 ms at 115 VAC, full load. Hold-up time, typical 13 ms at 230 VAC and 115 VAC, full load. No-load consumption <0.5 W by PS-ON control. The input-voltage load curve at 60 Hz permits 80% at 90 VAC, rising linearly to 100% at 115 VAC and remaining at 100% through 264 VAC. Apply this limit together with the thermal curves. The functional block diagram identifies a 65 kHz PFC stage and 70 kHz PWM stage. Protection Short circuit / overload 105–135% of rated output power; hiccup mode, with automatic recovery after the fault is removed. Overvoltage 52–59.5 V; output shuts down and requires re-powering to recover. Overtemperature TSW1 shuts down the output and recovers automatically after temperature decreases. TSW2 shuts down the output and requires re-powering to recover. Standby, Fan Supply and Control Signals 5 V standby output 5 V at 0.6 A without a fan or 1 A with 20.5 CFM cooling; tolerance ±2%; maximum ripple 150 mVp-p. Fan auxiliary supply 12 V / 0.5 A; tolerance −15% to +10% at a main-output load of 20% of the 20.5 CFM rated current. PS-ON logic Power ON: High, 2–5 V. Power OFF: Low, 0–0.5 V. Power Good / Power Fail TTL goes high after a delay greater than 10 ms and less than 500 ms after power set-up. It goes low at least 1 ms before output falls below 90% of nominal. The fan supply is dedicated to an additional external fan that cools this power supply, supports full-load delivery and promotes service life. Do not use it to drive other devices. Remote sense is provided at CN100: pin 1 is −S and pin 2 is +S; pin 3 is DC COM and pin 4 is PG. Follow the manufacturer installation instructions for sense wiring. This section does not specify a numerical line-drop compensation allowance or a separate PF connector pin. Cooling, Temperature and Environment Working temperature −30 to +70°C, with mode-specific derating; horizontal orientation. Operating humidity 20–90% RH, non-condensing. Storage −40 to +85°C; 10–95% RH, non-condensing. Temperature coefficient ±0.03%/°C over 0–50°C. Vibration 10–500 Hz, 2 G; 10 min per cycle, 60 min each on X, Y and Z. Operating altitude Up to 4000 m, with additional thermal derating above 2000 m. For the PCB type, the horizontal convection curve allows 200W up to 50°C, falling to 100W at 60°C. At 115VAC the separate convection line starts derating from 200W at 40°C and also reaches 100W at 60°C. The convection curves end at 60°C; the 70°C endpoint belongs to forced cooling. With 20.5 CFM forced airflow, the common RPS-300 / RPS-300-C curve permits 300 W through 50°C, then falls to 150 W at 70°C. This is a cooling-dependent continuous rating, not a timed pulse or a duty-cycle peak allowance. Above 2000 m, reduce the allowable ambient temperature by 3.5°C per 1000 m for fanless operation or 5°C per 1000 m for fan-cooled operation. Observe the lower load allowed by all curves.

Product Datasheet Download MEAN WELL RPS-300 Datasheet (PDF) The RPS-300 section is on PDF pages 1, 2, 3, 4, 5, 6, 7. Refer to the complete mechanical drawings and notes when planning installation. Model and Configuration Complete model RPS-300-15 Product type Single-output PCB medical AC/DC power supply with active PFC. Model code RPS-300 identifies the series; 15 is the nominal DC voltage; no type suffix identifies the PCB version. The 300W rating requires forced cooling and the specified input and ambient conditions. The model is not supplied as a top-fan or side-fan variant by this code; the cooling fan shown in the installation drawing is external. Primary-to-secondary insulation is 2 × MOPP. Suitability for BF applications requires appropriate consideration of the complete medical system; the component approval is not a guarantee of finished-equipment BF compliance. Model-Specific DC Output DC output voltage 15 V Current range, convection 0–13.33 A; subject to the enclosure and temperature limits below. Current range, forced cooling 0–20 A at 20.5 CFM. Printed output power ratings 200 W with convection; 300 W at 20.5 CFM. Apply all derating limits; the two modes are not interchangeable. Output adjustment 14.25–15.75 V, main output via SVR1. Ripple and noise, maximum 120 mVp-p. Voltage tolerance ±3.0%; includes set-up tolerance, line regulation and load regulation. Line / load regulation ±0.5% / ±1.0%. Efficiency, typical 90% at the standard measurement conditions. The catalogue lists rounded current and power values independently. Respect both limits and the lower allowable load imposed by cooling, input voltage and ambient temperature; do not increase a rating by recalculating voltage × current. Unless otherwise stated, specifications are measured at 230 VAC, rated load and 25°C ambient. Ripple/noise is measured with 20 MHz bandwidth and a 12-inch twisted pair terminated by parallel 0.1 µF and 47 µF capacitors. Input and Start-Up Input range 90–264 VAC or 127–370 VDC; 47–63 Hz AC. Power factor, typical >0.93 at 230 VAC; >0.98 at 115 VAC, full load. Input current, typical 3.5 A at 115 VAC; 1.8 A at 230 VAC. Cold-start inrush, typical 35 A at 115 VAC; 70 A at 230 VAC. Set-up / rise time 2500 ms / 30 ms at 230 VAC; 3000 ms / 30 ms at 115 VAC, full load. Hold-up time, typical 13 ms at 230 VAC and 115 VAC, full load. No-load consumption <0.5 W by PS-ON control. The input-voltage load curve at 60 Hz permits 80% at 90 VAC, rising linearly to 100% at 115 VAC and remaining at 100% through 264 VAC. Apply this limit together with the thermal curves. The functional block diagram identifies a 65 kHz PFC stage and 70 kHz PWM stage. Protection Short circuit / overload 105–135% of rated output power; hiccup mode, with automatic recovery after the fault is removed. Overvoltage 16.2–18.5 V; output shuts down and requires re-powering to recover. Overtemperature TSW1 shuts down the output and recovers automatically after temperature decreases. TSW2 shuts down the output and requires re-powering to recover. Standby, Fan Supply and Control Signals 5 V standby output 5 V at 0.6 A without a fan or 1 A with 20.5 CFM cooling; tolerance ±2%; maximum ripple 150 mVp-p. Fan auxiliary supply 12 V / 0.5 A; tolerance −15% to +10% at a main-output load of 20% of the 20.5 CFM rated current. PS-ON logic Power ON: High, 2–5 V. Power OFF: Low, 0–0.5 V. Power Good / Power Fail TTL goes high after a delay greater than 10 ms and less than 500 ms after power set-up. It goes low at least 1 ms before output falls below 90% of nominal.
